CAR-COUPLING..

`SPECIFICA'JTION forming part of Letters Patent No. 764,308, dated July 5, 1904.

W Application filed January 20, 1904. Serial No. 189,821. (No model.)

T a/Z whom [t may concern:

Be it known that we, ROGER F. SCANNELL, residing at Boston, Suffolk county, and PAT- RICK J. DUGAN, residing at Chestnut Hill, Middlesex county, Massachusetts, have invented certain new and useful Improvements in Car- Couplings; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others 1o skilled in the art to which it appertains to make and use the same.

This invention relates to -car-couplings; and

it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a plan View oi' the car-coupling. Fig. 2 is an end view of the means for operating the hook.

This invention relates to the class of couplings as shown in the patent to Patrick J. Du-

gan, No. 748,173, dated December 29, 1903, in which a coupling-hook A is provided which is pivoted to Work in a vertical plane.

B is the spring-pressed draw-bar to which the coupling-hook A is pivoted, and C is the guide in which the said draw-bar slides.

D is a portion oi' the car frame or platform to which the guide C is secured. In order to raise the coupling-hook out of engagement with a similar opposed coupling-hook, the ear* frame has a tubular guide E secured to it in a horizontal position at any convenient point adjacent to the coupling.

F is a rod which is journaled in the guide E and provided with a collar e.

is interposed between the collar c and the front end of the tubular guide and when the drawbar is pushed back in its guide against the pressure of its spring the rod F is pushed back longitudinally in the tubular guide against the pressure oi' the spring f.

A spring f The front end of the rod F has an arm G se cured on it, and the free end of this arm is pivoted to a bar (7, which is slidable in guides t, secured to the coupling-hook. The bar has stops rf, which limit its sliding movement erosswise of the coupling-hook. The sliding' movement of the bar permits the hook to be raised when the rod F is partially rotated in its tubular guide.

H is a handle whichis connected to the opposite end of the rod F from the arm G and which affords a means for operating it.

l/Vhat we claim is v 1. The combination, with a car-coupling hook pivoted to workin a vertical plane, of a stationary tubular guide arranged horizontally, a rod journaled in the said tubular guide and provided with an operating-handle, an arm secured to the said rod, and a bar carried by the said coupling-hook and slidable crosswise oi' it and pivoted to the said arm.

2. The combination, with a stationary guide,

a spring-pressed draw-,bar slidable therein, and a coupling-hook pivoted to the said d rawbar and Working in a vertical plane; olI a stationary tubular guide arranged horizontally, a rod journaled in the said tubular guide and provided with a collar, a spring between the said collar and the front end of the `said tubular guide, an operating-handle connected to the said rod,` an arm secured t0 the said rod, and a bar carried by the said coupling-hook and slidable crosswise of it and pivoted to the said arm. v 7 5 In testimony whereof we aiix our signatures in presence of two witnesses.
